WINDOW AND DOOR SCREEN.

Speccaton of Letters Patent.

Patented Nov. 10, 1908.

Application led December 9, 1907. Serial No. 405,739.

To all whom 'it may concern:

Be it known that I, DELMAR D. PINKHAM, a citizen of the United States, residing at Longview, in the county of Gregg and State of Texas, have invented a new and useful Window and Door Screen, of which the following is a specification.' y

. The present invention relates to window and door screens, and while particularly intended asan improvement on the structure disclosed in a patent No. 831,636, granted tov me on November 13, 1906, there are features herein set forth not necessarily restricted in their use to that structure.

The principal object of the present invention is to provide a knockdown screen, which can readily be put together bythe user, is strong, rigid and durable, and will permit the detachment and replacement of the netting so that new material may be more read ily substituted for that which has become worn out or broken. 4 l l The preferred embodiment of the invention is illustrated in the accompanying drawings, wliereinz Figure 1 is a rear elevation of a screen constructed in accordance with the present.

invention. Fig. 2 is a detail perspective view of a corner of the screen. Fig. 3 is a longitudinal sectional view through a p0rtion of one of the'rails. Fig. 4 is a cross sectional View on the line 4-4 of Fig. 3. Fig. 5 is a cross sectional view but illustrating the manner in which the netting holding strip is removed andlreplaced. Fig. 6 is a detail perspective view of the corner piece. Fig.`7 is a similar view of the corner reinforcement. Fig. 8 is a detail perspective view of a portion of one of;the side rails.

Similar reference numerals designate corresponding parts in all vthe figures of the drawings. In the present case, a window screen is disclosed, rectangular in form and consisting of angularly disposed side rails, each designated as a whole by the reference numeral 9. Each side rail is preferably formed of a strip of sheet metal and comprises a body portion 10 having along its inner margin an overhanging outwardly turned keeper or fiange 11 that extends over one face of the body. A right langularly disposed flange 12 is located longitudinally along the opposite -or outer margin of the body 10, and is doubled, as shown, thus producing a keeper 13 that overhangs the same face of the body over which the keeper 11 extends. The free edge of the fiange 12 or keeper is inturned towards the body, but is spaced therefrom, as clearly shown in Fig. 5.

' The adjacent ends of the various side rails are connected by corner pieces 14. Each corner piece consists of an larly disposed leaves 15 having outstaniig flanges 16 along their outer edges. These leaves are located against the bodies of the side rails, theirvinner edges being located beneath the keepers 11 and their outer flanges .16 being inclosed by the flanges 12 and keepers 13. Corner reinforcements in the form of bowed or ribbed strips 17 have angularly disposed end-portions or arms 18. These corner reinforcements are placedupon the corner pieces, the end portions 18 being disposed longitudinally ofthe leaves 15.

Wire netting, designated 19, is cut toa size so that its margins will extend over the keepers 11 of the side rails, and is bent about said keepers as illustrated in Figs. 4:'

vand 5. Netting retaining strips 20 are provided that are longitudinally beaded or channeled, as shown at 21.y yThe inner edges of these strips are engaged beneath the keepers 11 and clamped against the netting. The outer edges are engaged beneath the free edges of the outer keepers 13. ends of these stripsQO are located over the ends of. the corner pieces, and of the reinforcements 17, the end portions of said reinforcements engaging and being thus held in position by the strips.

rIhe'structure has a number of advantages. In the first place, it may lbe vshipped in knockdown condition and assembled by the user or retail salesman. This will be evident when it is consideredthat the ends or leaves 15 of the corner pieces can be readily fitted into the ends of the side rails, the corner reinforcements being placed against said cornerpieces, the netting located, and finally the various parts clampedv together by the holding strips 20. In introducin these holding strips, the edges are place in the keepers 11, and the outer edges are forced 'downwardly until they are engaged beneath the free edges, of the keepers 13. To detach in the channels 21- The A stood that various changes in the size, shape,

proportion and minor details of Iconstruction, may be resorted to without departing 'from the spirit or sacrificing any .l of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire' to secure by Letters Patent, is

1. A screen frame includingA aside rail, said rail being formed of a metal strip comprising a body having an outturned keeper along its inner margin' overlapping one side of said body, and an .angularly disposed doubled flange along its outer margin, the

A body having flanges outstanding doubled flange being also 'in the form of a keeperand having its free edge inturned and spaced from thebody of the bar, and a netting holding strip having an inner edge that engagesl beneath the outturned keeper of the body, and an outer edge that engages beneath the said free edge lof the doubled flange. 2. A screen frame including angularly disposed side rails, each rail comprising a l from the same side of the body and turned' toward the same, a corneil piece comprising angularly disposedv leaves, each. engaged between the body and the overturned flanges of one of the rails, and a netting holding strip associated with eachrail 'and having its edges interlocked with the said overturned Vflanges thereof, said flanges constituting 'means for holding vthestrip in place.

3. A screen frame including angularly disposed side rails, netting holding strips interlocked with the side rails and having longitudinally disposed channels in theirinner sides, a corner -piece comprising angularly disposed leaves interposed between the rails and the strips, and corner reinforcements located against the corner pieces and having angularly disposed terminal portions fitting in the channels of the strips.

4. A screen frame including angularly disposed side rails, each rail comprising a body having flanges outstandingl from the saine side of the body and turned toward the same, a corner reinforcement having angularly disposed end portions, and a netting .holding strip associated with each rail and having its edges interlocked witlilthe overturned flanges thereof, the end portions of said strips extending over the end portions of the corner reinforcement, said netting holding strips being held in place on the rails by their interlocking engagements with the flanges.

5. A sci'een frame including angularly disposed side rails, each side rail being formed of a metal strip and comprising a body having an outturned keeper along its inner margin, and an angularly disposed doubled flange along its outer margin, the doubled flange being also in the form of a keeper and having its free edge spaced from the body of the bar, a corner piece comprising angularly disposed leaves, each leaf being engaged between the body and the keepers of one of the side rails, a corner reinforcement located against the corner piece andhaving angularly disposed end portions, and a netting holding strip associated with each side rail and having an inner edge that engages beneath the outturned keeper of the body, and an outer edge that engages beneath the said free edge of theouter doubled flange, the ends of said strips covering the 'ends of the corner piece and the end portions 'of tlie'corner reinforcement.

6. A screen frame made up of independent side rails, each rail comprising a body having outstanding flanges with keepers formed thereon, corner pieces connecting the .side rails at each4 corner of thev frame, said corner pieces being provided with outstanding flanges which interlock with certain of the keepers of the side rails, reinforcements provided upon the corner pieces, and a netting holding strip associated with each side rail and engaging with the keepers thereof to hold the netting in place, said netting holding strips each having ,channels provided therein to engage and fit over the corner reinforcements. v

7. A screen frame made up of independent side rails, each comprising a body having flanges foi-ined thereon and constituting keepers, corner pieces connecting' the side rails at each corner ofthe frame and having an inter-fitting engagement with the rails, corner reinforcementsplaced upon the cornei' pieces, and a netting holding strip mounted 011 each side rail and engaging with the corner reinforcements to retain the saine on the corner pieces. v
